docs: def disp(name=None, idx=None):
      """displays selected data from (files written by) the class `CMADataLogger`.
  
      The call ``cma.disp(name, idx)`` is a shortcut for ``cma.CMADataLogger(name).disp(idx)``.
  
      Arguments
      ---------
          `name`
              name of the logger, filename prefix, `None` evaluates to
              the default ``'outcmaes'``
          `idx`
              indices corresponding to rows in the data file; by
              default the first five, then every 100-th, and the last
              10 rows. Too large index values are removed.
  
      Examples
      --------
      ::
  
         import cma, numpy
         # assume some data are available from previous runs
         cma.disp(None,numpy.r_[0,-1])  # first and last
         cma.disp(None,numpy.r_[0:1e9:100,-1]) # every 100-th and last
         cma.disp(idx=numpy.r_[0,-10:0]) # first and ten last
         cma.disp(idx=numpy.r_[0:1e9:1e3,-10:0])
